Repair manual KTM MINI 50 air/liquid cooled Art.-Nr. 3.206.028 -E
Resistor values of the ignition system - Stator
– Unplug the ignition stator and measure the resistance of the stator
using a digital measuring tool.
– The resistance must be 500 Ω ± 40 Ω at 20º C.
NOTE: it is not neccessary to take the stator out of the engine housing.
Ignition coil
– Undo the spark plug cap
– Measure the resistor of the secundary side of the Ignition coil
between high tension lead and mass of the coil.
– The resistance must be 2250 Ω ± 250 Ω at 20º C.
Measuring static ignition values with peak voltage adapter
Measuring conditions:
– cold engine
– seat and tank removed
– all connector and socket connectors and the ground connection in a
non-corroding condition
– kick the kick starter forcefully at least 5 times for each measurement
Check the pulse generator/charging coil for an output signal - one-pin
